New England regionalisms

: My family originates from central Vermont and New Hampshire (early 1700's) where I still live and I've noticed that many people don't know what I mean when I use these expressions. I would like to know their origin and compare meanings to see if it is different than how my family interpreted them. With us, if someone did something that was "...like s h i t through a tin horn!", it means they did a lot of it and got through it quickly. If someone "cut a pig in the ass", it means they made a poor decision, usually business related, that would end up harming themselves (if you cut a pig in the ass, you'll ruin the ham which is one of the best parts of the pig). "I'd milk her for what she gives" was used when discussing what to do about anything from a tractor or car to a milk cow that had reached the point of requiring more upkeep and repairs then were worth putting back into them. If one decided to "milk her for what she gives", it meant this was the last use until it broke down again. Then it would be re-cycled for parts, eaten, etc.
